COMBINE-D DRlLLlNG AND BORING MACHINE.

SPECIFICATION forming part of Letters Patent No. 319,502, dated June 9,1885.V

Application filed January 2, 1885.

To @ZZ whom it may concern.:

Be it known that I, GEORGE G. MORRISON, of Philadelphia, county ofPhiladelphia, and

and useful Improvement in Machinists Tools, of which the following is aspecication.

My invention has reference to machinists tools,but more specifically tocombined drilling and boring machines; and it consists in thecombination of a drilling and boring machine, both combined with thesame standard of supporting-frame, so that the same motive power orcounter'shaft may be used to drive either the boring or drillingmechanism, and in many details of construction, all of which are fullyset forth in the following specication, and

form part thereof.

The object of this invention is to so construct a single machine that itmay embody the principles of two machines required in nearly allmachine-shops, and by which the expense may be greatly reduced, as wellas the space required in the shop being diminished.

The combination hereinafter set forth does not in any way interfere withthe machine being used simply as a drilling-machine, neither does it inany wise interfere with the machine being used. as a boring-machine, andwhile it is possible to operate both the drilling and in practice theywould be used alternately or one at a time.

In the drawings, Figure l is a side elevation of a combined drilling andboring ma-w chine embodying my invention, and Fig. 2 is a sectional planview of same on line x x.

A is a counter-shaft, with its usual drivingpulleys and cone, by whichthe drill is driven.

B is the overhead horizontal shaft of the drill, and is provided on onevend. with conepulleys and upon the other end with a bevelpinion, C.

E is the main column Or frame of the machine.

K is the drill-spindle or tool-holder, and works through a bevel-wheel,D, adapted to mesh with the pinion C, the said spindle K having akeywayor groove,into which a feather or key on the said bevelwheel D works, bywhich the said spindle K may be moved ver- (Nomodel.)

tically through the said bevel-gcar, but is caused to rotate with it,the said construction being that employed in 'all drills. The saidbevel-wheel D is journaled in a sliding frame or box, G, which worksupon a guide, F, of`

the main frame, and may be moved vertically by a hand-wheel, h, andscrew H, so that the gear-wheel D may be moved into or out of contactwith the driving bevel-pi nion G. The bevel-wheel D is provided with anotch or lugs, d,

into or between which the end of a pivoted Y spring lever or catch, I,is allowed to enter after the box G has been slightly lowered. Vhen thebevel-wheel D is meshing with pinion C, the pin J of the main framecauses the lever I to be oscillated, so as to throw the same out ofcontact with the gear G, allowing it to rotate freely; but the moment itis lowered, so as to be free from said pinion C, the lever I leaves thesaid pin J, and a spring, l', draws the said lever int-o contact withthe lugs or notches of the bevel-wheel D, and locks its spindle fromrotation.

Instead of the lock just described, a simple lock (shown at I2) workingin a key way of the said spindle K may be used.l

K is a tool-holder on the bottom end of the spindle K, when the saidspindle is fed either automatically or by hand up and down by means ofthe gear L, of any ofthe well-known constructions.

M is a table to which the work is secured, and is pivoted or journaledat m to the adjustable frame N. rllhis table M is provided with aninternal gear, Mi, into which a pinion, O, secured upon a verticalshaft, O', works, the said shaft O receiving its motion from ahorizontal shaft, P, by means of a bevel-gear, O2, and the shaft P inturn receives its motion from the counter-shaft A by means of anadjustable sleeve, Q, which slips upon the ends of the counter-shaft Aand shaft P, coupling them together through the agency of the keys orkeyways It.

It is to be understood that I do not limit myself to any specificconstruction of drill, as the invention is to be adapted to the variousmakes now in the market. Neither do I limit IOL and D from the gear O rthe gear D, they may be made fast or loose upon their respective shaftor spindles by means of a clutch or notch of any suitable construction.Likewise the connection between the counter-shaft A and the table M, bywhich thelatter is rotated, may be greatly modified, if desired; and Iwould also remark that it is not necessary to my invention that thislatter motion be received from the counter-shaft A, as it could equallywell be received from the vertical shaft-gear with the overheadhorizontal shaft B; but while any or all of these modifications arepractical, and may be best adapt-ed to some machines, I however preferthe construction y shown.

\Hav ing now described niy invention, what I claim as new, and desire tosecure by Letters Patent, is-

l.l In a combination-tool comprising a drilling and boring machine inwhich cit-her may be used separately, the combination of adrill or toolspindle, mechanism, substantially as set forth, to rotate or preventrotation of said spindle, a face-plate or table, and mechanism,substantially as set forth, to rotate or prevent rotation of saidface-plate, substantially as and for the purpose specified.

2. In a combi11a tion-tool,a drill or tool spin-A dle combined withgearing to rotate it, mechanism, substantially as set forth, to separatesaid gears to arrest the rotation of thc spindle, 'and a lock to preventthe rotation of said spindle when the gears are separated, sul)hstantially as and for the purpose specified.

3. In a combination-tool, a drill or tool spindle combinedwith gearingto rotate it, mech anism, substantially as set forth, to separate saidgears to arrest the rotation of the spindle, a lock to prevent therotation of said spindle when the gears are separated, a face-plate, andmechanism, substantially as set forth, to rotate or prevent rotation ofsaid face-plate, substantially as and for the purpose speeied.

4. The combination of shaft B, having bevelpinion O, frame E, having aguide, F, box G,

screw H, to move said box, gear D, carried by,

said box, and spindle K, substantially as and for the purpose specified.

5. The combination of shaft B, having bevelpinion C, wframe E, having aguide, F, box G, screw II, to move said box, gear D, carried by saidbox, and a lock to prevent rotation of said gear D, substantially as andfor thepurpose specified.

6. The combinationofshaft B, havingbevelpinion C, frame E, havingaguide, F, box G, screw H, to move said box, gear D, carried by said box,lever I, spring I', pin J, and spindle K, substantially as and for thepurpose specitied.

7. The combination of frames E and N, faceplate M, havinggear M', pinionO, shaft O', gears O2, shaft I), counter-shaft A, and conmeeting-sleeveQ, substantially as and for the purpose specified;

In testimony of which invention I hereunto set my hand.

GEORGE G. MORRISON.
